Some things can only be done "in camera". Tilting to capture a scene with movement would seem like such a thing.
Other things can be approximated in post processing. The questions then are : what is the difference in cost, quality and time spent. Some might also think that the quality of time spent matters (typically that it is better to spend 10 more minutes with setting up your camera, than 10 more minutes editing with photoshop.)
*Shifting the lens to make buildings appear as if perspective was altered:
If a good ts lens costs $2000, what can be accomplished by purchasing a better (non-ts) lens and/or a camera of denser sensels, and doing the corresponding stretch in software? If the stretch is moderate, I would guess that the latter solution can be competitive.
*Shifting a lens for panoramas
How many are doing this the "right" way (fixing the lens, shifting the camera), and how much better are your results than using dedicated accessories for moving the camera + lens?
I am primarily interested in the tilt (not for fake miniatures), but the prices are stopping me.
